涩北一号气田是第四系不成岩地层,地层岩性疏松、欠压实、成岩性差、气层埋藏浅、分布井段长、气水界面复杂;地层承压能力低,易漏、易喷、易缩径;易漏井段为1110~1120m、1250~1300m及1300m以下。随着气田的开发,近年来在钻井中发现原... 涩北一号气田是第四系不成岩地层,地层岩性疏松、欠压实、成岩性差、气层埋藏浅、分布井段长、气水界面复杂;地层承压能力低,易漏、易喷、易缩径;易漏井段为1110~1120m、1250~1300m及1300m以下。随着气田的开发,近年来在钻井中发现原属正常地层压力层系的浅部,因发生异常高压,造成钻井中"上吐下泄"的复杂及事故,给开发过程中的钻井作业带来了极大的复杂和风险。 展开更多

Serotonin (5-HT), an important neurotransmitter, has been implicated in a wide range of disorders such as depression, anxiety, post-traumatic stress disorder (PTSD), and learning and memory disorders. Recent work of CAS researchers has shown that mice lacking serotonin are less anxious compared to control animals but retain fearful memories for much longer time. A study conducted by CAS researchers may contribute towards developing treatments for PTSD, where long lasting fearful memories bring constant pain and sufferings to individuals who cannot forget them. 展开更多
